Adjustable trigger assembly and method of adjusting pre-travel distance

Abstract

A trigger assembly apparatus for a firearm which allows adjustment of the pre-travel distance a trigger travels before initiating a firing sequence and method of making the pre-travel adjustment using the apparatus disclosed herein. The apparatus generally comprises a trigger and a trigger bow, with the trigger bow having at least one threaded receptacle in a front lateral portion thereof. The pre-travel adjustment can be achieved by rotating a threaded fastener within the threaded receptacle and the method of adjusting the pre-travel can be accomplished without complete disassembly of the firearm.

I claim: 
     
       1. A trigger assembly comprising:
 a trigger; 
 a bow having a first end connected to the trigger and a second end opposite said first end, said bow comprising:
 a front lateral cross member at the first end; 
 a rear lateral cross member at the second end; 
 a first side cross member extending between the front and rear lateral cross members; 
 a second side cross member extending between the front and rear lateral cross members; and 
 at least one threaded receptacle defined within the front lateral cross member. 
 
 
     
     
       2. The trigger assembly of  claim 1  wherein the front lateral cross member comprises a single, integral piece of material. 
     
     
       3. The trigger assembly of  claim 1  where the side cross members are substantially parallel to each other. 
     
     
       4. The trigger assembly of  claim 1  wherein the at least one threaded receptacle circumscribes an axis substantially parallel to a barrel axis of an assembled firearm when the trigger assembly is installed on said firearm. 
     
     
       5. The trigger assembly of  claim 1  where the first and the second side cross members are each connected to the front and the rear lateral cross members. 
     
     
       6. The trigger assembly of  claim 5  wherein the first and the second side cross members are each connected to the front and the rear lateral cross members with rounded corners. 
     
     
       7. The trigger assembly of  claim 1  wherein the at least one threaded receptacle comprises a first threaded receptacle and a second threaded receptacle. 
     
     
       8. The trigger assembly of  claim 7  further comprising a first corner formed by connection of the front lateral cross member to the first side cross member and a second corner formed by connection of the front lateral cross member to the second side cross member, and wherein the first threaded receptacle is positioned between the first corner and the connection of the trigger to the bow, and the second threaded receptacle is positioned between the second corner and the connection of the trigger to the bow. 
     
     
       9. The trigger assembly of  claim 1  comprising at least one threaded fastener for threaded engagement with the at least one threaded receptacle. 
     
     
       10. A trigger assembly comprising:
 a trigger; 
 a bow having a first end connected to the trigger and a second end opposite said first end, said bow comprising:
 a front lateral cross member at the first end; 
 a rear lateral cross member at the second end; 
 a side cross member extending between the front and rear lateral cross members; and 
 at least one threaded receptacle defined within the front lateral cross member. 
 
 
     
     
       11. The trigger assembly of  claim 10  wherein the front lateral cross member comprises a single, integral piece of material. 
     
     
       12. The trigger assembly of  claim 10  wherein the at least one threaded receptacle circumscribes an axis substantially parallel to a barrel axis of an assembled firearm when the trigger assembly is installed on said firearm. 
     
     
       13. The trigger assembly of  claim 10  wherein the at least one threaded receptacle comprises a first threaded receptacle and a second threaded receptacle. 
     
     
       14. The trigger assembly of  claim 10  comprising at least one threaded fastener for threaded engagement with the at least one threaded receptacle. 
     
     
       15. A method for adjusting trigger pre-travel on a firearm with a slide comprising:
 removing the slide from the firearm; 
 inserting a driving end of a driving tool into the firearm; 
 inserting the driving end into a socket of threaded fastener; 
 rotating the threaded fastener; and 
 removing the driving end from the firearm. 
 
     
     
       16. The method of  claim 15  further comprising positioning the driving tool above the firearm prior to inserting the driving end of the driving tool into the firearm. 
     
     
       17. The method of  claim 15  wherein the driving tool is selected from the group consisting of an Allen wrench, a ninety degree screwdriver, and a ratchet. 
     
     
       18. The method of  claim 15  further comprising installing the slide on the firearm after removing the driving tool from the firearm. 
     
     
       19. The method of  claim 15  further comprising orienting the driving end directed toward a muzzle end of the firearm.
